BAKER-GAGE.

To all whom it rnay concern:

Be it known that I, MARION F. Hronnn, a

citizen of the United States, residing at 'Salamanca, in the county of Gattaraugus and State of New York, have invented certain new and useful Improvements in Baker-Gages; and I do hereby declare the a raker age which will instantly indicate the condition of the raker teeth on being placed'in position.

Another object in view is the arrangement in a raker gage of means for adjusting the indicating part thereof so as to permit the I proper filing of the teeth.

-A still further object of theinvention is the arrangement of a raker gage having a folded portion designed tofitover the teeth of a saw, and an adjustable raker engaging and. measuring member adapted to permit the filing'of the raker teeth so that the same willbe the desired height in respect to the cutting teeth of the saw.

With these and other objects in view the invention comprises certain-novel constructions, combinations, and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawin s: Figure 1 is a perspective view of an em odimentof theinvention. Fig. 2 is a side View of the structure shown in Fig.. 1, the same being shown applied. Fig. '3 is an end view of the ga e shown in Fig. 2. Fig. 4 is a view disclosing a blank of part of the gage. Fig. 5 is a view disclosing a blank of the adjust.- able part of the gage. 6 is atop plan view of the gage shown in Fig. 1. Fig. 7

is a section through Fig. 6 on l1ne 77.

In. constructing an embodiment of the invention a plate, provided preferably with a rectangular aperture, is bent upon itself so as to form a substantially U-shaped member with a notch therein. In the notch is positioned an adjustable member having flangesslipping over part of the plate so as to guide the adjustable member as the same is moved. A suitable tension member I is provided for clamping the adjustable member in any desired position so as to perv Specification ot'Letters i'atenti Patented Sept. 19', 1-911.

mit the-proper operation upon all of the raker teeth ofthe saw.

In order that the invention may be more clearly understood an. embodiment of the same is shown in-the accompanying dra'wings in which 1 indicates t which the guiding frame 2 is made. In mak ng the guiding frame 2 the blank 1 is bent upon itself until a substantially U? shaped structure .is presented having a 'notch' 3 formed therein. In notch 3 isj'aror indicatranged an adjustable measuring to indicate ing member 4 which is designe e blank from the relative heights of the raker teeth-,and

also indicate what the heights of the raker teeth should be. Indicating member 4 comprises blank 5, shown in F1 5, and rollers 6'and 7, shown inFig. 6. ank 5 is bent for forming turned over portions 8 and 9 telescoping or sliding over the lower part of guiding frame 2 just'below opening 3, and together with connecting or top member 10 forms substantially a U-shaped structure. Blank 5 "is formed with projections 11 and 12 which are bent so as to form indicating members 1313 and 14-14, as well as roller supporting ears or journal members 15 and 16. Members 1313 and 1414 are formed with pointed ends which pass over scales 17 arranged on both sides of the guiding frame 2, and on opposite sides of the openin or notch 3. The ears l5 and -16 are provided withsuitable apertures in which the reduced ends of rollers 6 and 7 are positioned so that the upper edge of the rollers are in the same plane for permitting the use of instruments on either side, and indicatingon either side of the height of the raker teeth 18 of saw 19. Member 4 is designed to be slid up or down as the case may be for causing the upper edge of the rollers 6 and 7 to approach or recede from the upper edge of the guiding frame 2 and in order to retain member 4 in any position in which it is placed a thumb member 20 is provided which is threaded on a stud 21 rigidly secured to guiding frame 2 by any desired means, as for instance by bein riveted or upset at 22 as well as threaded Into member 2. Stud 21 projects through a slot 23 of member 4 so as to permit the free movement.

of member 4 whenever thumb member is loose.

In order to accommodate any of the raker I teeth 18 a slot 24 is providedintop or cross piece 10 and is made sufliclently large to permit the free entrance and Withdrawal of the tooth, but prevents any substantially longitudinal movement of the instrument when the tooth is projecting through the slot.

In sharpening and setting a saw itis desirable to have all of the cutting teeth of practically the same height, and to have the raker teeth of a slightly less height, so as to permitthe free removal of the chips or saw dust'. \Vhen cut-ting hard wood forinstance it is preferable to have the .raker teeth formed slightly shorter than'thc cutting teeth, while in cutting comparatively soft wood it is preferable to have the raker teeth considerably shorter than the cutting teeth. The raker gage embodying the invent-ion when placed in position clearly indicates the relative height of any particular raker tooth with the corresponding cutting tooth, so that the same may be filed off or otherwise acted upon as desired. Also by the adjustable feature of indicating mem; her i the exact amount of matter removed may be determined, or rather the exact distance between the height of the cuttingteeth and the raker teeth may be determined. After the indicating member 4 has been once set for any particular saw, and for any particular grade of wood "the thumb member 20 is tightened and the device is used o n a ll of the raker teeth successively until all of the same are in'the desired condition, the device being used without any adjustment or change whatever except the movement of the gage from one raker tooth to another. I

\Vhat I claim is: y

1. In a device of the character. described, a guiding frame formed with a notch therein, an indicating member arranged to telescope ever part of the frame and to partly occupy said notch, said indicating member comprising a substantially U-shaped portion formcdwvith a slot in one side thereof. and a pair'of upstanding ears, and a pair of parallel rollers spaced apart, said -U-sh aped portion being formed with a slot therein 0pposite the opening between said rollers for permitting the passage thercthroughand be tween said rollers of a saw tooth when the device is being operated, and a. clamping member for clamping the connecting member to the frame. V

2. In a device of the character described, a substantially U-shaped frame formed with 'a notch therein, an indicating member ar ranged to telescope over part of the frame and to partly occupy said notch, said indicating member comprising a substantially U-shaped portion formed with a slot for acconnnodating a. saw tooth, and a pair of upstanding ears, a pair of rollers journaled in said ears and arranged with a space therebetween in linewith the slot in said U- upstanding ears, and a. pair of parallel rollers spaced apart," said U-shaped portion being formed with a slot therein opposite the opening between said rollers for permitting the passage therethrough and between said rollers of a saw tooth when the device is being operated, and a. clamping member forclamping the indicating member to the frame, said clamping member being formed with a stemprojecting through a slot in said substantially U-shaped portion I ofsaid indicating member.

In testimony whereof I aflix my signature in presence of two witnesses.
